Airlines Criticise UK Air Traffic Control After Second System Failure Causes Flight Disruption

Airlines have strongly criticised the UK's air traffic control system after a second technical issue in two weeks caused widespread disruption to flights. The latest incident has prompted industry leaders to demand urgent reform and question the resilience of the nation's aviation infrastructure.

EasyJet stated that Monday's disruption "once again calls into question the resilience" of the air traffic service. Meanwhile, Wizz Air warned of a "national confidence crisis" in National Air Traffic Services (Nats), the public-private organisation responsible for managing the UK's airspace.

According to Nats, the disruption was caused by a "connectivity issue" at its Prestwick control centre in Ayrshire. The organisation clarified that this incident had "nothing to do" with a separate software defect that occurred at its Swanwick centre in Hampshire earlier this month.

Political and Industry Leaders Demand Answers

Prime Minister Andy Burnham expressed deep concern over the repeated failures, stating that further issues "cause even greater concern" regarding the UK's air traffic control and its leadership. When asked by reporters if he would seek to dismiss the head of Nats, Burnham described the situation as serious.

"These are clearly serious issues and they need to be fully investigated," Burnham said. He added that the Transport Secretary, Heidi Alexander, was taking the matter "extremely seriously" and that it was initially her responsibility "to get to the bottom of... and why there has been a recurrence."

Transport Secretary Heidi Alexander acknowledged that the situation was "deeply frustrating" for passengers. Meanwhile, industry representative body Airlines UK stated that both passengers and airlines "deserve better" service following "yet another Nats failure."

Demands for Leadership Accountability

The managing director of Wizz Air UK, Yvonne Moynihan, called for "urgent reform" of Nats and expressed a lack of confidence in its current leadership. When asked if Nats chief executive Martin Rolfe should resign, Moynihan suggested broader scrutiny was required.

"We need to look at the leadership at the top. But more than that, what are the board of directors doing?" Moynihan said. Jet2 chief executive Steve Heapy also called for "urgent and accountable" action to strengthen the infrastructure of the UK's air traffic control system.

Ryanair reiterated its demands for Rolfe to resign, asserting that he had failed to deliver "either a reliable system or an effective back-up." The airline reported that the latest outage affected 140 of its flights and impacted 25,000 passengers. British Airways described "yet another technical fault with Nats" as "disappointing."

Widespread Flight Cancellations and Passenger Impact

Data from aviation analytics company Cirium revealed that more than 150 flights were cancelled at UK airports on Monday, including 140 departures and 137 arrivals. EasyJet was the most heavily impacted carrier, cancelling 48 of its 670 scheduled departures. British Airways cancelled 13 of its 513 scheduled departures.

The Prestwick control centre, where the connectivity issue occurred, manages air traffic across northern England, Scotland, and Northern Ireland, accounting for approximately 42% of all UK air traffic. The other major Nats facility at Swanwick handles southern UK airspace, including flights approaching London's Heathrow and Gatwick airports.

The previous Swanwick incident was highly severe, affecting intercontinental and long-haul travel, and leaving hundreds of thousands of passengers stranded. Nats later reported that the earlier disruption was caused by a software defect that occurred "in the space of a millisecond," resulting in corrupted data. At the time, Rolfe declined to resign, describing the software defect as "very, very obscure."

Compensation Rules and Ongoing Investigations

The UK Civil Aviation Authority (CAA) has indicated that passengers affected by the latest disruptions are "unlikely" to receive financial compensation. The regulator explained that the technical issue is "likely to be considered the result of 'extraordinary circumstances' under passenger rights rules."

While airlines are still legally required to look after delayed passengers, they are not obligated to pay compensation for cancellations directly caused by the Nats incident. The CAA is currently conducting an independent review into the resilience of the UK's air traffic control system, with the final results expected to be published "within six months."

A Nats spokesperson apologised for the disruption, stating: "In the real world, we accept technology can and sometimes does fail. Our job is minimising disruption where possible. What isn't acceptable is any incident where safety is compromised - this is always our first priority." Nats confirmed the underlying connectivity issue has been resolved and the system is operating at full capacity, though knock-on delays remain.
